DUMP-CAR.

Specification of Letters Patent.

Application filed February 10, 1909 Serial No. 277,050.

.able doors disposed longitudinally of the hopper, with the main or prnnory doors of and less width than the bottom opening supplemented by auxiliary doors for fully closing the same. A bottom opening of large area thus controlled by doors of high efilciency which are manipulated in com paratively small space.

A further characteristic is the chute mech anism of novel design Which coiiperatcs with the laterally movable doors'i'or dumping the load at one or both sides of the car or at the center. as may'he desired.

Another and very important feature is the adaptation of o. centersill undeiirame to a car adapted for center Well as side dumping, thereby providing for'rnore direct and economic transmission of the drarlt forces than heretofore.

The invention includes door and chute operating mechanisms of novel design; a hopper embodying scv .ral structurally novel features; a top chord of improved construc tion, and other features of novelty referred to hereinafter.

in the accompanying drawings, Figure l is a view partly in side and partly in tional elevation of a portion of a dump oer embodying the invention, and Fig. 9. is in top and sectional plan of the some. Figs. 3 to 6 are cross sections taken on lines 3-3,

-'l4. 55 and 6.6, respectively, of Fig. 1.

Referring to the hawings, 2 are the draft beams and 3 the end portions of the center sills here shown as inward continnations of the draft beams. Portions 3 of the center sills coincident with the mouth of the hopper are oli'set downwardly and laterally from end portions 0, being connected thereto by the yoke-shaped-part or iii-H1 91 e, Figs. 1 and 3. Provision is thus had for trans niitting the. draft forces from one end the car other without obstruc ng the hopper, without intert door mechanism. Furtherin sills time move in and out behind dependi or side dumping, alternative operations not heretofore attained with continuous center sills.

are the sheets forming the side Walls of the hopper with their lower portions disposed inwardly and downwardly, forming the sloping floor extensions or ledges 6 which are braced or supported from beneeth by the angular longitudinal plate or inein ers 7. The latter are provided. with side extensions connected by straps 5 with side sheets 5. Ledges 6 detine the width of the hopper bottom opening.

8 are the sloping end floor plates which pass upwardly over holster-9 and hanging from the inner ends of these floor plates is the ii-shaped plate 10. The doors close around these plates the latter forming the "end Walls of that portion of the hopper bottom of which the doors when closed term. the sides and bottom.

Back of or mitwerdly from each of plates 10 is the verti al transverse plate or sheet ll to which end plates 8 secured. The plate embraces and extends beneath Sills 3 to which it is secured,as indicated at; 11, Plates ll term the end Walls of the space through which the material fiOWS from the car and also serve as tenders for preventing it from overflowing the trucks. in. midi tion, these plates support various parts of the dumping mechanism. and slots or openings therein serve to guide some of the movable ports; all ZZS'Wlll presently. appear.

The door feature s embodied in a lower or main doors a pair of srippl mental doors 13. Doors 12 are movable orally bodily and so inclined converge and close together at the center of the car. The doors extend from end to end or. the bottom opening, and is provid F with the vertical end members M l shaped plat-cs 1O the doors close one preventing the material from flowing over ce the door extremities. Vi hen closed together the transverse area of doors i2 is less than the Width of the hopper hot-tom opening, end doors 13 are provided for closing the remainder of said opening.

Doors 12 are spirced d fiized floor ledges 6 so t doors 13 hi. the ledges main doors. One result of this arrangement is that as the main doors move laterallyor outwardly from closed position the inclination of the doors 13 increases, thus accelerating the downward flow of the load. then the main doors are opened only partially for a center dumping operation, as in Fig. 5, both sets of doors remain in inclined position, the inclination of doors 12 being the same as when closed, and the inclination of doors 13 increased, as above indicated. When the doors are fully open for dumping at either one or both sides of the car, as in Fig. 6, the main doors 12 are moved outwardly clear of the supplemental doors so that the latter turn downward into vertical position, with means presently to be described for afiording the main doors a simi lar movement, with the result that the full. transverse area of the hopper bottom opening is available for discharging the load. It is characteristic of the invention that the several doors are parallel longitudinally of the car and that the parallelism is maintained throughout their various movements.

The means for supporting and actuating the main doors will now be described. Each end of each of these doors has trunnion connections with wheels 15 and 16 located at the outer side of transverse plate 11, the trunnions moving through slots 1.7 and 18 in the latter. l'Vheel 15 is preferably located a little above or back of the center of the door and wheel'lG at the'upper or outer edge thereof. Hence, the inner or lower portion of each door extends inwardly and downwardly for a considerable portion of its width from wheel 15. \Vlieel 15 is supported on a track 19 secured to plate 11 beneath slot 17, and wheel 16 moves between guides 20 and 20 also secured to plate 11 below and above slot 18.

Mounted on trunnion 15 of wheel 15 is the internally threaded sleeve 21 through which extends the horizontal transverse screw shaft 22. One of these shafts is provided for each end of the door, the shafts at each end of the hopper alining, as shown in Fig. 3, and each at its outer end geared to a longitudinal shaft 23 which is geared to the corresponding shaft at the othcr end of the hopper. Each of shafts may be operated by-a hand wheel 2 having its shaft 25 geared to one end thereof, as in Fig. 2. Thus doors 12 and 13 at either side of the center of the car may be operated without disturbing the other doors.

Provision is made for operating all the doors simultaneously, the same consisting of a two-part transverse shaft 26 geared to the extremities of shafts 23, with the parts of shaft 26 connected when desired by clutch .27 provided with a suitable operating lever 28. When this clutch is thrown in, all of the doors may be operated simultaneously closed.

'to be turned thereby between lugs 38 by either of the hand wheels at, while when the clutch is out the door operating mechanisms are disconnectechand are quite separate and distinct from each other.

A chute of novel design is provided for dumping the load beneath the center of the car, or for deflecting the same to either or. both sides of the track, and is embodied in fixed and movable chute members positioned beneath the doors. The fixed chute members are inclined downwardly and outwardly from sills 3, the inclination thereof being preferably about the same as the doors when Above fixed members 30 are the movable chute members 31 which are immediately beneath the lower edges of doors 12 when closed. Each of chute members 31 is supported at each end by two wheels 32 at the outer side of plate 11, the latter being slotted horizontally at 33 through which the wheel axles project, wheels 32 moving on track 34% supported by sills 3.

For dumping the car at one side of the track, as in full lines in Fig. 6, or at both sides of the track as shown partly in dotted lines in the same figure, chute members 31 are in inward position and form upwardly converging continuations of the fixed mom-- her 30. So that when dumped at. one side only, the material discharging over the then closed doors or floor members is deflected laterally over the active side of the chute and falls clear of the track. When all of the doors are fully open, as in full lines at the left-hand side. of Fig. 6 and dotted lines at the right-hand side, the material dis charges at both sides.

For a center dumping operation, doors 12 are opened only partially, and at the same time movable chute members 31 are moved apart, as in Fig. 5, the movement of the doors and chute members extending to. the space or clearance between center sills 3, and these sills together with the vertical sides 31 of the chute members form a vertical passage or drop for the material.

The movable chute members are prefer-- ably actuated by the same mechanism that operate doors 12, with means for operatively connecting said parts who": th; ante members are to be moved, as in fig. The construction in this regard is here shown consi-sting of a shaft at each end of the hopper beneath screw shaft 22, with an arm 30 projecting from the axle of one of chute wheels 32 and at its upper end forked and movable on shaft Also movable on said shaft and" embraced by the fork arm 37 which turns with the shaft and is adapted pro-' jecting from the end P1 of door 12. A mechanism of the character described is provided for each end of each movable chute section, so that either or both of the latter may be moved simultaneously with doors cease-e.

12, or may remain at rest when the doors are moved. Shafts at opposite ends of the hopper are geared to longitudinal shafts 39, beneath and parallel with shafts 28, with one of shafts 39 provided crank 4-0, connected by linlr ell with. an operating lever 42. Y

The outer portion 18 of each of slots 18 is curved upwardly so that after doors 12 open wider than is required for the center dump.- ing operation, the outer edge of each door moves upward, thereby permitting the door to oscillate on trunnion 15 until it finally assumes a vertical position back or outside of the then vertically hanging supplemental door 13, as in full lines at the left-hand side of Fig. 6. The radius of the curved slot extension 18 is struck from the center of trunnion 115 when the door is vertical, so that the latter is free to oscillate and its lower edge may swing outwardly, as in dotted lines at the left-hand of Fig. 6, to give clearance for boulders or lumps of material striking the door as they discharge from the car, and depression 18 at the base of curved portion 18 afiords an extreme movement of this sort.

The hopper sides and floor ledges may be reinforced by stays l5 and 46, the latter be ing preferably somewhat wider and arranged at thecenter of the hopper to receive thetransverse' tie or reinforcement 47,

connecting the opposite sine sheets-5.

The top chord for each of the hopper sides consists preferably of a strip or plate of heavier gage than sheets 5 and riveted to the inside of the top edge of the latter at 48, the cord being inclined inwardly and up? wardly as indicated at so, with its top portion curved outwardly and downwardly at in substantially semi-circular form, and with the downwardly curved edge secured at intervals to the outer face of the top edge of side sheets by straps 5]. This form of chord provides a substantial reinforcement, and there is no danger of shovels, buckets, or other loading apparatus catching the same when moving away from the car.
